An electric pump begins humming, immediately a fine mist of water-based insecticides appears out of the nozzles located in the ceiling of the barn. The light air currents in the barn slowly swirl the mist around and flying insects begin dropping out of the air, dead. After a minute the pump shuts off and the mist vanishes.

As the farm manager and a client approach the area where the client's horses are boarded, they find the animals are calm and content and the barn is free of flying insects.
